Overview
Mansion Days is a 3D dating sim for players who enjoy slow-burn harem stories with a domestic setting. The tone stays grounded, focused on personal drama rather than fantasy spectacle.
Story
A man moves into a large mansion shared by three sisters — Zoe, Siera, and Raven — and their mother Daisy. Old tensions and unspoken history run through the household, and staying there means slowly uncovering what each woman is hiding and how their feelings toward him and each other begin to shift.
Gameplay
Play unfolds through point-and-click exploration of the mansion, moving between rooms and time slots to find story events tied to each woman. Conversations and choices shape how relationships develop, while an RPG-style progression layer gives structure to your daily routine inside the house.
Features
- Rendered in 3DCG with animated scenes built from multiple camera angles
- Sandbox-style exploration of a single, detailed household setting
- Parody elements woven into an otherwise grounded family drama
- Separate storylines for each woman, each advancing at its own pace
Installation
1. Extract and run.
Changelog
v0.0.9
- I’m so happy about it. This is the longest update I’ve ever worked on. For the first time I thought, why not pack several animations into a single event? So the new Debbie event has 3 animations! Three animations! In another Party event I made 2 animations, but one of them somehow ended up with 7 camera angles. The events turned out pretty long. I tested them, and if you read with one hand it takes about 30-40 minutes per event, so roughly an hour for the whole update. I think that’s a solid amount of content.
- I’m also super excited to finally add new languages. We’re talking TEN brand new languages: Spanish, Portuguese (Brazilian), Italian, Polish, Japanese, Korean, Russian, French, German, and Danish! Phew, I think that’s all of them. In the future I’ll try to add even more, Chinese for example. The translation might not be perfect, but I hope you enjoy it anyway.
